Radon Fan Electricity Cost Per Month
Residential radon fans commonly draw somewhere in the range of 40 to 100 watts and run continuously, which works out to roughly 29 to 72 kilowatt-hours a month. At a typical Pennsylvania residential electric rate, that generally lands in the range of a few dollars to around ten dollars a month, though your specific fan model and utility rate will move that number.
Because the fan runs continuously by design, rather than cycling on and off like most household appliances, this is one of the more predictable ongoing costs of owning a mitigation system. It is also small enough relative to a typical utility bill that it rarely factors meaningfully into the decision of whether to mitigate.
See our cost guide for the installation cost itself, which is the larger, mostly one-time number that matters more for budgeting than the modest ongoing electric draw.
Common questions
Does a bigger house need a more powerful, more expensive-to-run fan?
Fan sizing depends more on the sub-slab conditions and system design than square footage alone. A qualified installer selects the fan based on the vacuum needed to depressurize your specific slab, not a general size chart.
Is there a way to check my specific fan's actual draw?
The fan's nameplate lists its wattage. Multiplying that by 24 hours and days in the month, then by your utility's rate per kilowatt-hour, gives a reasonably accurate estimate specific to your system.
